Why my PC turn on by itself during sleep?

[pcwin]

I have clicked the start>sleep in my windows 7.

When the pc is sleeping, it wakes up by itself. I guess there are some scheduled task by windows 7.

Why?

Is there a way to see why or what task caused my PC to turn on by itself?

How to see what task was done during the auto wake up?

Thanks

Its probably Windows update kicking in at its scheduled time, 03.00 am, check your WU settings

Because I don't use sleep/hybernate - can WU wake the PC? How can it wake while sleeping itself?

On the sleep options.
Enable/dissable wake timers.

I am a bit confused. Do I need to do all the steps in your link? There are many steps there.

Is there a setting that I can "do not wake up once I put pc to sleep".

My problem happened only after I reinstalled windows 7 recently. For the past 5 years there is no such problem.

Apparently there is a problem now, and that tutorial covers everything.

Step 4-5 will help here.

If you still can't get it working as you intend to, then check out the rest of the tutorial.

I did step 4 and step 5 (part 1 and 2)

What are the things that is causing awake? I am not sure how to see the details

Maybe it is your mouse.

In device manager, right click the mouse under power properties, and tell it not to wake up the pc.

"In device manager, right click the mouse under power properties" Where is this? I cannot see power properties in device manager.

In my earlier post #8, anyone else have problem viewing screenshots from imgur?

I attached the same screenshot into this forum:

Right click the mouse

It is either your keyboard, mouse or network card from the looks of it. Or some other USB device if not these. Best is to disable waking with these first and see if it work alright.

You should be able to disable waking from them - check the tutorial on how to. See Step 6.

1. I thought even if keyboard and mouse are enabled to wake the computer, if I do not touch it, it will not wake the computer correct? I am away from the computer and I am sure nobody touched the keyboard and mouse.

2. If I disabled keyboard and mouse "allow this device to wake the computer", I assume I cannot wake by pressing mouse or keyboard buttons, how can I wake the computer?

 

[GokAy]

I would think power button, but, hmm, try disabling mouse and network card. Leave keyboard.

Mouse spuriously does things which can wake PC.

It's more likely the network card than anything else. It defaults as waking the computer on install.

And this is a fresh install...

What if the function of network card? What default schedule does it do during night time that needs to wake up the pc? (I put my PC to sleep from 11pm to 7am, during my sleeping hours)

 

[Mellon Head]

If the network card is set to wake the PC from sleep, then a signal from the network can wake the PC. It can happen at any time. It may take five minutes, it may take and hour, but eventually there might be activity on the network which will wake the PC.

Check the following setting on your network card:
